S, Sham-operated; Nxpre, pretreatment Nx (60 or 120 days after renal ablation); Nx+V, untreated Nx; Nx+L, losartan-treated Nx; Nx+LH, Nx treated with losartan+hydrochlorothiazide; Nx+AHHz, Nx treated with amlodipine, hydrochlorothiazide, and hydralazine. Results expressed as Mean ± SE. a, p<0.05 vs. Sham; b, p<0.05 vs. Nxpre; c, p<0.05 vs. Nx+V; d, p<0.05 vs. Nx+L and e, p<0.05 vs. Nx+LH.
